Would Saw Palmetto Counteract Propecia?

Please can you explain scientifically how taking saw palmetto can be counter productive to propecia. You have said in some replys that taking even green ‘MAY’ interact with propecia and stop it working to its full potential. I wonder wether everyday things will then, from a lot of fresh veg and fruit or other things.

I do not know of any antagonism of saw palmetto and Propecia (finasteride 1mg). The side effects of both are similar so you might see more sexual side effects when you double up on both medications. I don’t know where I’ve said anything different…
